Application March 22, 1935,. Serial No. 12,358 1 Claim. (01. 292-158)This invention relates to door lock mechanisms of particularadaptability to vehicles wherein the requirements of construction arelimited by. the width and thickness dimensions of the door post and thepresence of sliding windows.

The trend in automotive construction is toward smaller door pillars. Thespace heretofore available for the lock mechanism is not only restrictedin size hut must now accommodate the window pane in such manner that thepane extends into the path of the mechanism, it is therefore on objectorthis invention to provide a lock mechanism which will interfit with andactually straddle is a horizontal section taken along the F lines 22 oiFigure l;

2i vis a view taken along the line 3-4 of Figure 2;

Fig. i is a plan view of the interior handle partially broken away toshow the hinge thereof;

Fig. 5 is a section along the line d--li or Fi ure 1;

d is a sectiontaken along the line 6-t of Fig. i;

Fig. l is a detail section similar to Figure 2 showing the lock cylinderin looking position;

Fig. 8' is a plan view of a modified form of exterior handle, and

Fig. 9 is a section taken along the line 9-8 of Figure t.

t and i2 refer to the interior and exterior walls respectively of adoor. having a lock and latch mechanism therebetween for engagement witha keeper member 3 carried by a door post t. A handle h is pivotallymounted at 6 in a casting l secured to the inner well i in such way thatwhen the handle is in door latching position the outer surface of thehandle is substantially flush with the wall l. Integral with the handle5 is a bent arm t the end of which has sliding en- 9 8 opposes.retraction of the bolt ll and returns it to latching position uponrelease of either handle 5 or M.

The handle ill is also preferably embedded in the door so that the outersurface thereof is substantially flush with the wall 2.

A look if! is carried by the handle it near its outer end. The cylinderof the lock extends inwardly of the casting l3 and has an extension itadapted for rotation to a. position directly abutting the end of thebolt in to oppose retraction thereoil The extension II also acts todirectly oppose withdrawal of the handle M and loch it from the casting42 as best seen in Fig. l.

Pivotally mounted within the door is a bell crank 22 having one endadapted for rotation to a point directly opposing withdrawal or the boltit. The bell crank 22 is actuated by a push rod 23 frame point withinthe'contour of the handle fl 4 it will be seen that the pane of glass 24iuter-= fits with the locking mechanism and that the handles 5 and i lreside adjacent opposite surfaces thereof.

The modification shown in Figures 8 and 9 is similar to that previouslydescribed with the exception of the handle a. In this form. the handleMa has a rounded outward surface so that its edges all merge into thecontour of the body. This handle preferably resides horizontally so thatthe palm of the hand is upward when gripping it for pivotal opening.

What I claim is:- Y

A door lock mechanism for a hollow vehicle I door having a window paneslidable therein with the edge of said pane extending into close proximity to an edge of said door, said mechanism.

comprising a bracket mounted on a wall of said.

all

actuating said latch bolt, a bracket mounted on the opposite well ofsaid door and on the opposite side of said pane, the second bracketbeing adapted to support a handle for actuating said latch bolt, saidlatch bolt having a projecting element thereupon, a bell crank pivotallymounted in the space between the edge of said pane and said edge of saiddoor, said bell crank. being adapted to he moved to a position where oneend thereof engages said projecting element and directly opposesmovement of said latch bolt,

and a. push rod mounted on the second named bracket and-connected to theother endof said bell crank for moving the same.
